Application December 6, 1938, Serial No. 244,266

3 Claims.

The present invention relates to new and improved radiators and moreparticularly to such devices constructed in a manner to be reversed on avehicle to change the flower water there'- through.

As is well known, foreign substance in a radiator caused by rust, scaleand particles of oil fromthe motor, usually settles on top of theradiator core and very seldom penetrates into the cellular structureand, due to the continual circulation of water in one direction, suchforeign substances will become permanently embedded in the core. Over aperiod of time this condition usually results in overheating of theradiator caused by faulty circulation of the water and oftentimes theradiator will leak as a result thereof. The herein described radiatorbeing reversible and readily removable for reversing will greatlyimprove the above conditions. Reversing the position of the radiatorplaces the clogged top of the core to the bottom and changes the flow ofwater which, through assistance of the water pump, forces out anyobstruction that has a tendency to accumulate and settle in the core.-Also, a periodic reversing of the core will, toe. large extent, minimizethe accumulation of foreign substance therein. j

It is, therefore, the primary object of the invention to provide aradiator for use with an oil or gasoline water cooled motor that isreadily reversible whereby the direction of flow of water therethroughcan be changed to prevent partial obstruction of the core of theradiator.

A still further object of the invention is to provide a reversibleradiator including 'baffled tanks with extra hose and filler connections-which when not in use, are capped by novel means forming part of theinvention.

The invention will be fully and comprehensively understood from aconsideration of the following detailed description when read inconnection with the accompanying drawing which forms a part of theapplication.

In the draWing- Fi e 1 is a front elevational view with parts in tion ofa radiator constructed in accordance with the present inventien.

Figure 2 is-a side elevational view of the radia tor with the lower partin section, and

Figure 3 is a top plan view of the radiator disclosed in Figure '1.

Referring to the drawing for a more detailed description thereof,wherein there is illustrated the preferred embodiment of the invention,the new and improved reversible type radiator is indicated generally bythe reference numeral 5 and includes top and bottom sections 6 and 1respectively of identical forms. 'I'hesections 6 and I include headertanks 8 and 9 respectively, each tank being formed with a baflie plateIt) 5 more clearly illustrated in Figure 2 of the drawing, said tankscommunicating with the cellular structure of the radiator core H in theconventional and well known manner.

The top section 6 further includes a filler 10 connection l2extendingtherefrom and closed by a suitable cap 13, said cap beingattached to the section by means-0f a chain or the like H. The bottomsection 1 is likewise formed with a filler connection l5 and cap l6attached to the section 15 by means of the chain or the like ll.

Each filler connection l2 and 15, respectively, has attached thereto byany desired means, overflow pipes l8 and I9, respectively, each pipecarryinga pet cock valve 20 and 2| respectively, one 20 of which isadapted to'be shut off when not in operation. In other words, when theradiator is in the position illustrated in Figure l of the drawing, theoverflow pipe I!) is not in operation and consequently the pet cock 2|remains closed, 25 with the pet cook 20 and its associated pipe inoperation and therefore open.

Inlet and outlet connections are formed on each of the sectionst and 1one of which is adapted to be closed by an expansible plug when 30 notin use. In Figure 1 of the drawing, the top section 6 is illustratedwith an inlet connection 22 supporting thereon a rubber hose 23, and anoutlet connection 24 closed by the expansible plug 25. The position-ofthe inlet and outlet 35 connections on the bottom. section I issubstantially reversed to that used in the top section 6. 0n the bottomsection I the outlet connection 26 supports the rubber hose 28 and theinlet connection 21 is closed by the expansible plug 28. 40 Referring toFigure 2 of the drawing, there is more clearly illustrated the type ofexpansible plug used for closing the connections not in use, said plugcomprising an expansible cylindrical shaped member 29 formed of rubberor similar 45 material and having extending therethrough a threaded bolt30. A metallic washer II is carried by the bolt and is held inassociated relation with the member 29 by means of the wing nut 22.

38 on the other end of the radiator. The brackets are formed withopenings for receiving "the connecting members 31 for bolting theradiator to the frame 38 of the vehicle.

When desiring to reverse the position of the radiator from thatillustrated in the drawing the bolts 31 and hose connections 23 and 28are removed. The reverse end of the radiator is then attached by meansof the bolts and brackets 33 and 34 and hose connections substituted forthe expansible plugs 25 and 28'. The expansible plugs are thenpositioned in the connections 22 and 26. Thus connection 21 will becomethe inlet and connection 24 the outlet for the radiator in its reversedposition so that the flow of water through the radiator will bereversed. Naturally, when reversing the radiator the rust and scale thatwas formerly on the top of the core will be on the bottom thereof sothat the reversing oi the flow of waterthrough the radiator will forcethe rust and scale from the core and it being of a metallic substancethat is heavier than water will sink to the bottom of the tank and lodgein the filler neck I 5. In other words, a trap will be formed in thebottom-most portion of the radiator below the outlet connection and thedislodged rust and scale can be periodically removed from the fillerneck. I t

It is to be noted that the filler caps are formed with a washer 39 bestshown in Figures 1 and 2 of the drawing whereby a leakproof connectionis provided to prevent loss of water through the bottom section.

Also it will be understood, of course, by those skilled in the art thatvariations in the hereinabove described device involving thesubstitution of the invention nor exceed the scope thereof as expressedin the appended claims.

What is claimed as new is: 1. An automobile radiator comprising, acasing having top and bottom header tanks, a core sup- DOrted betweensaid tanks and in communication therewith, means for removably attachingsaid radiator to an automobile for reversing the position thereof, and aplurality of connections associated with said tanks adapted to permitcirculation of water through said core.

2. An automobile radiator comprising, a casing having spaced top andbottom header tanks, 9. core supported between said tanks and incommunication therewith, a filler connection extending fromsubstantially the central portion of each tank, a plurality ofconnections extending from the rear walls of said tanks adapted topermit circulation of water from a motor through said core, and meansfor removably' attaching said radiator to said automobile for reversingthe position thereof.

3. An automobile radiator comprising, a casing having top and bottomsections, each section formed with a header tank therein, a coresupported between said sections and in communication with said tanks,filler connections extending substantially centrally of said sections,outlet members extending from the rear walls of said sections adapted toreceive a hose forconnection with a motor to permit circulation of waterfrom said motor through said core, and means for removably attachingsaid radiator to the automobile for reversing the position thereof.
